讲座主题：Estimating and Projecting Disparities in Demographic Outcomes Using Bayesian Methods
讲座内容简介：It is crucial to monitor demographic and global health indicators accurately to optimize resource allocation. This is especially so in developing countries where the improvement of these health indicators is most needed. However, estimating and validating these indicators are fraught with challenges, one of which is the paucity of accurate data. The Bayesian modeling approach implemented in my research provides more objective, data-driven insights into estimating demographic and global health indicators. I provide a set of important analyses and fill the previous research void on selected indicators. I take account of the data quality that varies across different sources and infer the levels and trends of indicators in countries and periods with limited data by data-rich country-years. The resulting estimates provide new insights into the sex ratio at birth and mortality globally. International agencies have used the methods and results for policy making.
准确监测人口和全球健康指标对于优化资源分配至关重要，发展中国家尤其需要改善这些健康指标。然而，估算和验证这些指标充满了挑战，其中之一就是缺乏准确的数据。研究中采用的贝叶斯建模方法为估算人口和全球健康指标提供了更加客观的、以数据为导向的见解。我进行了一系列重要分析，填补了以往对选定指标的研究空白。考虑到不同来源的数据质量各不相同，我利用数据丰富的国家年份来推断数据有限的国家和时期的指标水平和趋势。由此得出的估算结果为了解全球出生性别比和死亡率提供了新的视角。国际机构已将这些方法和结果用于政策制定。
讲座嘉宾简介：Dr. Fengqing Chao is an Assistant Professor in the School of Humanities and Social Science at The Chinese University of Hong Kong (Shenzhen). Dr. Chao received her Ph.D. from the Saw Swee Hock School of Public Health, National University of Singapore. She has been actively collaborating with United Nations Population Division and UNICEF since 2012. Since 2024, Dr. Chao has started to collaborate with the WHO Sexual and Reproductive Health and Research Department. She develops complex statistical models for sparse and noisy data for population indicators (e.g., sex ratio at birth, under-5 child mortality rate, adolescent mortality rate) across countries over time. She has several publications in PNAS, Lancet Global Health, PLoS ONE, and BMJ Global Health.
